To all whom it may concern."-

Be it known that I, MARIUS JEAN BAP- .TISTE Bsnnanomeitizen of theFrench Re.

public, residing at Paris, in the Republic 5 of France, have inventednew and useful Improvements in Clutch Devices for-Motor Vehicles, ofwhich the following is a speciremovable wire or like'member Y issefication. This invention relates" to clutch devices for motor vehiclesof a known type: in which pivoted-levers are used to positively bringthe clutching discs'or like members to the 'unclutched' positionf Saidpivoted levers extend through radial grooves provided in a sheet metalmember whlch is:

- like ,member dis osedin said groove acts as an abutment or the saidpivoted levers, whereby the latter do not engage at their free ends withthe actuating thrust-bearing when the vehicle is clutched all undue wearof said thrust bearing being thus efiiciently so prevented. I I In theaccompanying drawings, given-by Way of example:

Fig. 1 is an axial section of a clutch device constructed in accordancewith the invention.

Fig. 2 is an end view "of the same, some 7 means on the sheet metalmember for reparts being broken aw'ay.-

The general construction of theapparatus is well known. A is thefly-wheel 40 of the engine having secured thereon the sheet metal discB. Levers N pivoted on the latter may be depressed at their inner endsby. the outer ring 0 of a ball thrustbearing mounted on a sleeve V whichcarries trunnions P and may be shifted axially by means of a fork alongthe part S. On the disc glate B, is secured asheet metal member notchesB through which the levers N extend. Said levers N act through themedium of adjusting screws Qupon pushers G secured to the disk E wherebysaid disk may be positively moved to the left (Fig.

Y 1) for unclutching in opposition to the action ofsprings G. When thethrustprovided with radial slots or bearing 0 is returned to the right,the levers N are released and the springs act to clutch together theclutch members EEPLL n v According to the present invention, the sheetmetal disc R- is provided with a flange R forming a circular groove inwhich a cure ly held in position. The arrangement is such that thelevers N will come into contact with said wire when they are released bythe-thrust bearing 0 and forced to the right by the springs G. The wireY will thus act to limit the stroke of the levers N. towards the thrustbearing 0 in such 'manner'that in the normal posltion of the operativeparts of .the clutch i. 0. when the vehicle is clutched, said leverswill not come into contact at their free ends with the actuatingthrust-bearing 0. The wear of said thrust-bearing is' thus efiicientlyprevented.

Having now described my. invention, what I claim as new and desire tosecure by Letters Patent is 1. In a clutch device for motor vehicles,

the combination of clutching members, rocking levers adaptedto act onthe same, a thrust-bearing adapted to push said levers in one direction,return springs adapted to -move said levers in the opposite direction,

a sheet metal member having radial slots through which the levers areadapted to extend, a circular abutment member adapted to limittherocking movement of. the levers r towards the thrust-bearing and tainingsaid'abutment member in position. 2. In a clutch device for motorvehicles, the combination of clutching members, rocking levers adaptedtov act on the same, a thrust-bearing adapted to push said levers in onedirection, return springs adapted to move said levers in the o positedirection, a sheet metal member aving radial slots through which thelevers are adapted to extend and a ring-shaped wire adapted to limit therocking movement of the levers towards the thrust-bearing, the sheetmetal member being rovided with a flange adapted to retain sai wire inoperative position.

In testimony whereofl have signed my name to this specification. MARlUSJEAN-BAP'HSTE BARBQU,
